It should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

Hereinafter, with reference to the accompanying drawings will be described in detail a sodium lamp and a method for manufacturing the same according to the present invention.

1 is a view showing a sodium lamp according to the present invention, the sodium lamp as shown largely comprises a discharge tube 10, the outer glass tube 20 and the lamp head 30.

The discharge tube 10 has a structure in which a glass tube having both ends penetrated therein is a U-shaped bone fractured state.

The reason why the inner surface is made of the sodium layer 11 is to remove the impurities in the discharge tube 10 containing the impurities and increase the purity so that light emission of the light in the discharge tube is made clear.

The outer surface is composed of the silicate layer 12, the silicate is a pollution-free silicate having a self-determining ability to decompose organic matter, the light emitted from the discharge tube by removing impurities in the space between the discharge tube and the outer glass 20 to increase the purity This is to increase the sharpness of the.

A pair of conductive wires 31 drawn from the lamp head 30 are inserted and sealed at the inlets of both ends of the discharge tube 10, and a filament electrode 32 is formed at the ends of the conductive wires 31.

On the other hand, the above-described filament electrode 32 is coated with alkaline soil oxide of self-heating type to heat itself.

The outer glass tube 20 is a cylindrical glass tube, one end of which is blocked in a convex shape, the other end of the open structure, the inner transparent infrared reflecting film 22 is laminated on the outer glass film 21 It's a structure.

The outer glass tube 20 having the above-described structure is coupled to the lamp head 30 when the discharge tube 10 is accommodated through the opening.

At this time, the discharge tube 10 accommodated by the outer glass tube 20 is supported by the first support 40 and the second support 50 to maintain a symmetrical structure in the center without movement in the outer glass tube 20. .

Meanwhile, both ends of the first support 40 and the second support 50 are respectively mounted on the upper and lower portions of the glass tube 20 by horizontal forces applied to the inner circumferential surface of the outer glass tube 20 to support the discharge tube 10. do.

However, the first support 40 is bent in the same radius as the bent discharge tube 10 so that the surface in contact with the bent portion of the discharge tube 10 is maximized to support the discharge tube 10 stably. The second support 50 is a disk-shaped structure that can be completely inscribed and inserted into the inner peripheral surface of the outer glass tube 20, or as a plate-shaped structure that can be inserted into the inner peripheral surface of the outer glass tube 20 only partially discharge tube ( The conductive wire is allowed to penetrate at a position corresponding to both ends of 10), and a hole in which a predetermined length portion of both ends of the discharge tube 10 is inserted is formed.

The lamp head 30 is inserted into a power socket (not shown) to apply the power delivered to the power socket to the filament electrode 32 connected to the discharge and the inside by the wire 31.

As power is applied to the two filament electrodes 32, when the arc discharge occurs in the discharge tube 10 to reach a constant temperature, steam is generated in the solid sodium 13 bonded to the inner wall of the discharge tube 10. As the pressure of the sodium vapor in the discharge tube 10 increases due to the continuous generation of steam, the yellow electric light gradually becomes stronger.

At this time, the pressure of the sodium vapor in the discharge tube 10 reaches a stable state when the temperature in the discharge tube 10 is 260 degrees.

When the pressure of sodium vapor in the discharge tube 10 reaches a stable state, the discharge tube 10 generates bright strong light with excellent energy efficiency at low power.

Producing the outer glass tube 20 is made (S20).

Finally, after the external glass tube 20 is covered with the discharge tube 10 and accommodated, an open inlet is inserted into an external power socket to be coupled to the lamp head 30 to which power is applied, thereby sealing (S30). ).

Figure 3 is a flow chart for explaining in more detail the steps of manufacturing a discharge tube in the method of manufacturing a sodium lamp according to the present invention.

Meanwhile, when the sodium layer 11 is formed on the inner wall of the discharge tube 10, the step of forming the silicate layer 12 on the outer surface is performed (S14).

As the silicate layer 12 is formed on the outer wall of the discharge tube 10 in step (S14), it is a pollution-free quartz having a self-cleaning ability to decompose organic materials, thereby removing impurities in the space between the discharge tube and the outer glass 20, thereby purifying Increasing the degree increases the sharpness of the light emitted from the discharge tube.

In the above-described step (S13), the step of forming the solid sodium 13 on the inner wall of the discharge tube 10 is performed at the same time.

In addition, a protective gas, which is an inert gas, is injected into the discharge tube 10 to protect the electrode coupled in the step described later.

When the solid sodium 13 reaches a constant temperature by arc discharge in the discharge tube 10, the solid sodium 13 generates steam to increase the pressure in the discharge tube 10 so that the electric light becomes gradually brighter and stronger.

After the step (S14), as shown in Figure 4 the inlet portion of the discharge tube 10 is a wiring operation of the conducting wire is made (S15).

That is, a pair of conductive wires 31 drawn through the lamp head 30 are inserted into the inlet of the discharge tube 10 by a predetermined length and sealed.

Subsequently, as shown in FIG. 5, by connecting a vacuum system to the exhaust pipe 14 having the discharge tube 10 introduced at an end thereof, the vacuum system is operated to completely discharge all the gas in the discharge tube 10 to discharge the inside of the discharge tube 10. Keeping the vacuum state is performed (S16).

5 is a view illustrating a process of evacuating the gas inside the discharge tube.

Appropriate current is applied to the conductive wire 31 wired in step S15 to decompose the alkaline soil oxide of the filament electrode 32 coupled to the end of the conductive wire 31 to be discharged to the outside. When completed, the appropriate argon gas is injected to insulate and destroy the gas at a higher voltage to achieve a glow discharge, thereby maintaining a vacuum state as the exhaust inside the discharge tube 10 is completed.

Here, glow discharge is a phenomenon in which primary colors of light are generated by filling a gas of low pressure in a glass tube of vacuum and reaching a plasma state when flowing a current.

When exhaust of the discharge tube 10 is completed in step S16, the exhaust pipe 14 that is inserted is removed while leaving only a predetermined length (S17).
